This is our pal nitrogen he goes through alot everyday to take care of us.
When there is any type of precipitation, thats when he sneaks into the soil.
First, he makes a new friend named bacteria.
All together they form together and make annomia.
And another friend named hydrogen.
Along the way he makes some new friends called elements. He forms with them so that they can help cells in plants. This is called Nitrogen Fixation.
Do you remember ammonia? When we combine it with bacteria and oxygen, it makes something new that plants can eat . Then the animals eat the plants. This is called Nitrification.
When the plant or animal passes away, the nitrogen goes back into the ground. Then another bacteria turns it back into ammonia. This is called amonification.
Then the process repeats. Lastly, if there is any left over nitrogen, it goes into the air.
